FIELD OF THE INVENTION

The invention relates to cloud storage solutions, and more particularly, to a cloud storage solution with integrated security protocols to prevent unauthorized disclosure of sensitive and regulated technical data.

BACKGROUND OF THE INVENTION

Various forms of technical data must often be handled in compliance with certain governmental regulations. Increasingly, companies are reliant on cloud and other electronic document handling systems for the management of technical data. This is problematic in relation to this governmentally regulated data for a number of reasons. It is generally recognized that commercially available public cloud document and file storage, management and collaboration systems contain a comprehensive range of features and enterprise quality security that are impractical if not impossible to design, implement and maintain by any single enterprise or organization for its own documents and files containing such technical data and for purposes. Some commercially available public cloud systems merely contain features and functions that reflect a rich and leveraged history of solving a multitude of needs and concerns with regard to the storage, management and collaboration of documents and files, but also they are continually enhanced to incorporate the best available security and updated features at competitively maintained prices. These commercial offerings are consistently greater in function and far less in cost than those of companies not competing in this industry can achieve through their own individual efforts.

Unfortunately, these “best of breed” public cloud storage, management and collaboration solutions, as well as the specific functionality incorporated within these solutions, some of which could enhance compliance with the various confidentiality and security requirements of those laws and regulations and the administration and reporting requirements of those of laws and regulations for governmentally regulated technical data, have not been available for use where documents and files contain technical data defined in said governmental regulations. The very features of shared platforms, cloud disbursement of data, and ubiquity (and therefore anonymity) of access that have been viewed as positive attributes of cloud solutions generally have been viewed instead as antithetical to certain governmental regulatory schemes aimed at safeguarding sensitive technical data in compliance with those laws and regulations. Use of these resources has been judged as automatically resulting in what regulators categorize as impermissible handling of sensitive data in a manner that will or could result in security and confidentiality breaches due to the lack of mandated security controls and otherwise reasonable steps to ensure confidentiality.

As a consequence of the unavailability to those possessing documents and files with governmentally regulated technical data of leading public cloud document and file storage, management and collaboration subscription solutions, those possessing such technical data have been forced to implement various, inadequate alternatives or to otherwise forego benefit the public and their companies' interests in possessing and productively using such technical data. Some have avoided any electronic storage of governmentally regulated technical data, maintaining only “paper” copies of documents and materials containing such data. Others have maintained electronic copies, but have done so often in non-encrypted formats and hoped that through stealth and luck those documents and files would not be disseminated in violation of the government regulations. Still others have chosen not to engage in activities subject to such regulations.

Still other enterprises and organizations have attempted to implement and maintain “dark clouds,” which are private computer networks that attempt to capture some of the security, efficiencies and functionality of the best commercial offerings. Such offerings, however, have a substantially greater cost and significantly less functionality and security than could be available in the market from commercial providers if not for the regulatory prohibition.

Deficiencies in known systems indicate that: (1) there would be substantial cost savings, enhanced security, and less administrative burden if companies dealing with documents and files containing governmentally regulated technical data could collaborate in the use of those documents and files via common cloud computing practices that are widely recognized at the enterprise level as “best-in-class” to foster high productivity, performance and regulatory compliance; (2) encryption and use restrictions alone are not sufficient to achieve regulatory compliance when using cloud solutions; and (3) the cost of non-compliance, and therefore the lack of a solution to the unavailability of a leading commercial document and file collaboration solution, is high.

Accordingly, there exists a need for a fully functional, public cloud-based document and file storage, management and collaboration system for documents and files containing governmentally regulated technical data.

DETAILED DESCRIPTION

As illustrated in FIG. 1 , one embodiment of the present invention is provided. FIG. 1 depicts a document and file storage, management, and collaboration government regulation-compliant hosting platform 16 within a third party hosting platform 20, both of which platforms are physically located on servers or similar devices, which are located within a territory located within the scope of those government regulations. Some embodiments of the invention may be configured for storage and communication of classified data as well as controlled data. This control may be part of the implementation of the system according to one embodiment of the present invention and, consequently, dictates how data (customer content) is handled by the application provider and the hosting platform provider. In such a system, the government regulation-compliant hosting platform 16 may receive certificates from the application provider and the hosting platform provider confirming compliance, and/or may track IP addresses and other geographic indicia to monitor host location and access points. In some embodiments, confirmation of user compliance with predefined data security protocols will be automated to track transmission of data, verify user URL, and periodically check names and information.

Such embodiments could provide individual lists with training support maintenance consulting and third party certification that no names are on a preclusion list. Alternatively, they could provide access to a preclusion list to the customer to allow them to vet their own users.

Such a platform 16 may be configured with software, firmware, or hardware that prevents unauthorized access of technical data by IT staff and platform providers. Users of a system configured according with one embodiment of the present invention would be assured by the system that neither the application provider not the hosting provider will violate the predefined data security protocols; this also means that, through use by customers of the user and document permissions features that control access, use, movement, etc. of both users and documents, the customer can ensure that unauthorized persons do not have non-regulatory compliant access or possible access to documents containing controlled technical data. In some of these embodiments, primary users are capable of limiting access to controlled technical data so as not to provide access beyond the extent necessary for the end user. In some of these embodiments, the primary users are capable of dynamically and immediately increasing or decreasing an end users access in order to accommodate changing demands.

Embodiments of the present disclosure may identify the hardware associated with an authorized user. Hardware identification may comprise the identification of one or more hardware components of an authorized user's system, including the CPU, bios and motherboard and may vary from specific identification to identification of general characteristics of such hardware. A change in the hardware configuration of an authorized user may, in embodiments, be used to prevent the user's access to the encrypted data, trigger an alert or prompt the user to authorize the new configuration for access. Two-factor authentication, single use pins, two-channel authentication or other enhanced-security measures, as would be known to those of ordinary skill in the art, may be used to reauthorize a changed hardware configuration in some embodiments.

Controlled technical data may only be accessed by such authorized persons. The system according to one embodiment of the present invention, controls for this in two ways:

-   -   1. Through the implementation of the application provider and         hosting provider controls described above with regard to         authorized hosting local; authorized persons; authorized transit         of documents containing governmentally regulated technical data;         and     -   2. Through user and document restrictions (also referred to as         permissions) that the customer can place on both users and         documents, the customer can ensure its users that those         documents are not accessible, are not used, and are not moved         except in compliance with predefined data security protocols.

The government regulation compliant Hosting Platform 16 referenced in FIG. 1 maintains governmentally regulated technical data in encrypted format. In various embodiments of the present invention, encryption may be Encryption at rest (stored content): 256 bit AES encryption (Rijndael algorithm) Encryption in transit: up to 256 bit SSL encryption (https transfer). The encryption of documents stored on the system configured according to one embodiment of the present invention, ensures compliance with TLS standard 1.0. (Transport Layer Security (TLS) is a protocol that provides privacy and data integrity between two communicating applications. It's the most widely deployed security protocol used today, and is used for Web browsers and other applications that require data to be securely exchanged over a network, such as file transfers, VPN connections, instant messaging and voice over IP).

Embodiments of the present disclosure may also provide multilevel key management. Such embodiments may utilize a unique dataroom key, which may be generated during creation of a dataroom, which, in embodiments, may be synonymous with the secure viewer discussed elsewhere in the present disclosure. In other embodiments, a dataroom may be used herein to refer, generally, to the secure connection between a host platform and an authorized user. Such a dataroom key may be used to encrypt documents and be itself stored in an encrypted file system. The dataroom key may be further encrypted with a master key, which, in embodiments, is split into multiple parts, without all of which the information encrypted therewith may not be decrypted. Such a master key may be distributed between several persons to provide enhanced security. In embodiments, where a specific citizenship may be required for access to the underlying data, the persons having portions of the master key may all be of a uniform citizenship of the type required for authorized access. In other embodiments, the master key holders may be senior officials of the hosting platform organization.

Encryption implements a Multilevel Encryption Key Management, as follows:

-   -   1. Unique data room-key which is generated when the data room is         created;     -   2. Documents are encrypted with the applicable data room key and         stored in file system (256 bit AES encryption);     -   3. The data room key is encrypted with the system master key;     -   4. The master key is generated during installation of the         customer's data room center that allows for the creation of one         or a multitude of data rooms.

FIG. 1 further illustrates governmentally regulated technical data 22 being transmitted in encrypted format between a secured private database 14, such as might be maintained by private or governmental organization, to government regulation compliant Hosting Platform. It should be understood that the embodiments of the present invention may be deployed on various database platforms and are not limited to specific database architectures.

In the embodiment illustrated in FIG. 1 , individual Computing devices 18 controlled by users are permitted by the enterprise or organization, as defined in a controller 12 that controls the secured private database 14, to access the technical data in the Hosting Platform 16 and thereby receive controlled technical data from, and transmit controlled technical data to, the governmental regulation-compliant Hosting Platform 16 in encrypted form and in compliance with the established rules.

As illustrated in FIG. 2 , an enterprise controlling the secured private database configured according to one embodiment of the present invention controls the transmission of controlled technical data to and from the Controlled Hosting Platform from that secured private database and its permitted users (those using individual computing devices), as well as by controlling who will be, and who will continue as a permitted user).

As illustrated in FIG. 3 , a system 10 configured according to one embodiment of the present invention is provided for cloud based controlled file storage with tamper proofing and auto reporting functionalities. In the system, an enterprise controller 12 controls individual access 18, a database 14, and a governmental regulation compliant Platform 16. The controller 12 provides tamper proof auditing of governmental regulation compliant hosting platform 16. This tamper proofing is a result of limitations on the system such that the system is not accessible for editing or elimination by a customer. In embodiments, customers are not allowed access to that portion of the application that could be used to edit or eliminate information on users, documents and events in the use of the document. Encrypted technical data 22 is transferred between the governmental regulation-compliant hosting platform 16 and technical data secure database 14. Individual computing devices 18, which may include but are not limited to personal computers, workstations, mobile phones, tablets, smart watches, or similar devices, may, subject to permissions granted by the controller 12, access the governmental regulation-compliant Hosting Platform 16 and access data from it securely.

As illustrated in FIG. 4 , a host platform architecture may be provided comprising a firewall 30, a load balancer 32, dual application servers 34,36, dual AD-Controllers 38,40, a Network Attached Storage Device 42 and a Database server 44. A second firewall 46 may also be disposed between the application severs 34,36 and the AD-Controllers 38,40, Database Server 44, and Network attached storage 42. Those of ordinary skill in the art would be aware of other configurations that would provide comparable security and access.

In one embodiment, technical information is provided to a user on an individual computing device via a secure viewer. One such viewer is described in U.S. Pat. No. 7,865,827, which is incorporated by reference herein in its entirety for all purposes. Such a viewer allows the user to review documents, but not download them or store them locally. Similarly, displayed documents may have integrated watermark features, either visible to the user or occult. Watermarks may be dynamic, in that they may change during the course of viewing so as to embed user, time, location, device, and other data, so as to provide evidence in case of breach. Furthermore, the system is configured to trace each action and provide documentation to auditors or enterprise administrators. As the view interactacts with the controller, the controller is able to compartmentalize technical data and permissions in a highly granular way, facilitating permissions for specific tasks, documents, document viewing, and document storage. These use restrictions are chosen by the subscriber to the service with regards to individual users, user groups, datarooms, dataroom centers, and documents and files within and comprising such technical data. Such a system may be configured with an encoded email or similar messaging system.
